DERAILING DEVICE.

Specification of Letters Patent.

Patented July 25; 1911.

Application filed February 1, 1911. Serial No. 605,923.

To all whom tt vmay concern:

Be it known that I, LYMAN II. CoNNELLr, a citizen of the United States, residing at Osiertield. in the county of Irwin, State of Georgia, have invented certain new and useful Improvements in Derailing Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to derailing devices.

The object of the invention resides in the provision of a derailing device adapted to be associated with'a railroad track siding to prevent the passage of a train from the siding on to the main track when the switch controlling entranceY to the siding from the main track is in closed position.

A further object of .the invention resides in the construction of a derailing device of the character named which will elfectively accomplish the purposes for which it is intended and which is adapted to be operated simultaneously with the switch which controls the entrance from the main track to the siding in which the derailer is disposed.

With these and other objects in View, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters of reference denote. corresponding parts in the several views; and in which,

Figure 1 is a plan view of a section of a main track and siding with the invention associated therewith; Fig. 2, an enlarged plan view of a fragment of the siding andl the derailing device, the latter being shown in inactive position in full lines and in ac tive position in dot-ted lines; Fig. 3, a section on the line 33 of Fig. 2;l Fig. 4, a detail perspective View of the plate included in the derailing device.

Referring tothe drawings, A indicates the main track and B the siding. Entrance from the main track to the siding is controlled by means of a switch C which is actuated by means of a lever 10 operatively connected to a draw rod 11, which latter is secured to the pivoted switch points 12 and 13. Pivotally mounted upon an extension of one of the ties adjacent the draw rod 11 is an angle lever 141, one arm of which is operatively connected to said-draw rod 11 so that as the switch C is lactuated from 011e position to another, the/angle lever 14 will be oscillated. Mounted on adjacent ties'b'etween the rails of the siding B is a'base plate 15, and upon this base plate is secured a pair which receive the tongues 2O and 21 re-.

spectively. The inner side portion of the plate 22 is provided with a downward extension 25 for a purpose that will presently appear. The top face of the plate 22 is of substantially arcuate formation and has formed therein a diagonal groove 26 and a longitudinal groove 27. When the plate 22 is moved toward the adjacent rail of.

the siding a portion thereof will overlie the tread of said rail, while the extension 25 will engage the side of the rail and thus limit the movement of the plate 22 in one direction. When the plate 22 is disposed in overlying relation with respect to the adjacent'rail of the siding, the terminals of the groove 26 are disposed respectively on opposite sides of said rail. Pivotally mounted upon the base 15 is an angle lever 28, one arm of which is operatively connected with the plate 22 by means of a V shaped lateral extension 29 secured to said plate. Mounted upon adjacent ties of the siding B between the angle levers 14 and 2S is a plate 30, and pivoted upon this plate is a two-arm lever 31, one end of which is connected to the angle lever lll by means of the link 32, while the other end is connected to the angle lever 28 by means of the link 33. By this construction, it will be apparent that when the switch C is moved to closed position, the plate 22 will be shifted so as to overlie the adjacent rail of the siding and thus be -in position to effect the derailment of a train passing from the siding to the main track during the closed position of the switchv C. However', when the switch (l is moved to open position, the plate 22 will be shifted toward the center of the siding B and as a result will be without eifect on trains passing from the siding the main track by wey of the switch WVhat is claimed is:-

The combination with e main track and e siding of e switch controlling entrance to the siding from the main track, operating means for the switch, a shiftuble derailing device located in the siding, Laid device comprising apeir of spaced guide rails' eX- tending transversely of the siding, a plete slidably mounted between said guide rails and adapted to overlie one of the reils of the siding When disposed at the limit of its movement in one direction', said plate liev-4 ing en arcuate upper fece provided With a groove extending diagonally thereof and vleaving its ends disposed on opposite sides of the rail of the siding when the plateV overlies 'said rail, an angle lever pivotally eeeneo mounted adjacent seid plete7 connections be 20 tween the plete :md one arm of the angle lever whereby the oscillation of the lette@ will move the plate to and froml overlying relation with respect to the rail of the siding, and connections between the other erm of said angle lever and the operating ineens for the switch, Whereby the movements of said switch to closed and open positions Will shift seid plate to and from overlying position with respect to the rail of the siding 30 respectively. A

In testimony whereof, affix my sigheture, in presence of two Witnesses.
